Police refused to say how she was murdered, though a source has told the media that authorities are examining the possibility that she was raped — likely as she was reportedly missing her clothes.

Additionally, she was allegedly set on fire, with burns to her head, hands, and feet when she was found.

District Attorney Joseph Early, Jr. urged the public to be cautious, considering that police don't yet have a suspect and are not yet sure if this was a random act:

"We have a horrible set of facts, horrible circumstance. We don't know if this was a random act. We are asking residents of Princeton and surrounding areas to use an abundance of caution. We are concerned about the safety of our town residents and visitors that enter our town. Pay attention to surroundings. If you see anything suspicious or out of place, contact police."

Tragically, Marcotte's body was found just a half mile from her mother's home, the same place she had left between 1:00 and 4:00 p.m. local time on Sunday to go for the jog in the first place.

Marcotte's employer, Google, also released a statement about her death, sharing:

"Vanessa Marcotte was a much loved member of the Google team, working in our New York office for the last year and a half, and known for her ubiquitous smile, passion for volunteer work and love of Boston sports. We are deeply shocked and saddened, and our thoughts are with her family and friends."

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
